Madison Company offers durable stainless steel housed optical liquid level sensors that provide a single point, Push-Pull, switched sensor output for high pressure ap-plicaions. This sensor is designed for aggressive environments, capable of with-standing high and low temperatures and mechanical shock. These liquid sensors provide a low power signal, making these optical sensors ideal for micro-controllers, when needing to detect the absence or presence of clean, non-coating liquids. An infra-red LED and phototransistor ensures dependable optical coupling when the sensor is in air to eliminate false readings. When the sensor tip is immersed in liquid, the phototransistor will switch the out-put state.
